Sharpening device for razor blades



Oct. 27, 1931. J. B. RHODES SHARPENING DEVICE FOR RAZOR BLADES FiledFeb. 4. 1929 Patented Oct. 27, 1931 JAYnnHoDEs, or xALAMAzoo, MICHIGANSHRPENING (DEVICE FOIR RAZOR BLADES Application-filed February 4, 1929.Serial No. 337,327.

The main objects of this invention are:

First, to provide a sharpening device for razor blades andthe like whichis highly eiicient and atthe same time capableof easyv manipulation.

Second, to provide a sharpening device in which the blade is held inproper relation to various kinds of sharpening elements, that u is,-flexible straps such as razor straps or sharpening elements presentingnon-flexible surfaces.

Third, to provide a sharpening device having these advantages which isvery simple and economical in its parts and at the same time strong anddurable in use. l

Objects pertaining to details and economies of my invention willdefinitely appear from the description to follow. The `invention isdefined in the claims.

A structure which embodies the features of my invention is clearlyillustrated in the accompanying drawings, in which:

portions being broken away to show structural details.

eccentrically relative to the axis of the roller or are substantiallyspaced from the axis of the roller. On these pivots I mount a carrier 7,stop shoulders 8 being provided on the roller for limiting the swingingmovement of the carrier.

The carrier is provided with a holder for a blade such as 9, whichconsists of a cross member f 10 and a blade clamping member 1] which isslidably mounted on the carrier and provided with keepers 12 engagingwith lugs 13 on the carrier. The member 10 is provided with studs 14while the clamping member 11 is longitudinally slotted at 15 to receivethese lugs'. The lugs are adapted to engage the openin gs commonly foundin certain vtypes of safety .razor blades.

With the parts thus arranged the Carrier and roller are supported forlimited relative pivoted and swingingmovement." The roller` has a recessor flattened portion 16 between the pivots and adapted to provide bladeengaging shoulders 17. These shoulders swing downwardly upon the edge ofthe blade as indicated in Fig. 4 and hold it in engagement with thestrap.

In use the device is pressed upon the sharp-y ening element f andreciprocated back and forth thereon. Assuming that it is laid upon thestrap or other sharpening element with the carrier in advance of theroller or in the direction of the first stroke, the initial movementwill cause the roller to swing up to the firmly and in proper relationto the strap. On reversing the stroke the carrier is swung vover theyroller and the parts assume the opposite position,that is, the carrieris Vswung into a position in advance of the roller and i vpositionshownin Fig.- 4 holding the blade l My improved sharpening device iseconomical in its parts, is very convenient to use and is highlyeiiicient. I have not attempted to illustrate or describe certainmodifications or adaptations as it is believed that this disclosure willenable those skilled in the art to embody or adapt my improvements asmay be desired.

Having thus described my invention what I claini as new and desire tosecure by Letters Patent is:

l. Ina sharpening device, the combination with a handle, of a rollerrotatably mounted on said handle and provided with radially projectingears and having a recess in its periphery between said ears, and a bladecarrier pivotally mounted on said ears, said roller beingfprovided withstops limiting the swinging movement of said blade carrier, sain car ierbeing adapted to support a blade with the edge thereof to be sharpenedadja cent the roller and positioned to be engaged by one edge of saidrecess.

2. In a sharpening device, the combination with a handle, of va rollerrotatably mounted on said handle, and a blade ca rier pivotally mountedon said roller, the axis of the carrier being radially spaced relativeto the axis of the roller, spaced stops on said roller coasting withsaid carrier, said roller being pro vided with a flattened portionbetween the pivots of the carrier, said carrier being adapted to supporta blade with its edge to be sharpened in position to be engagedby theflattened portion 0I" the roller.

3. In a sharpening device, the combination with a handle, of a rollerrotatably mounted on said handle, and a blade carrier pivotally mountedon said roller, the axis ot the carrier iicing radially spaced from theaxis of the holder, the carrier being provided with a blade holderadapted to support a blade with its edge to be sharpened adJacent theroller, the roller having peripherally .spaced blade engaging shoulders.

In a sharpening device, the combination with a holder, of a rollerrotatably mounted on said handle and provided with radially pro'ectingears and peripherally flattened be-V l with a handle, of a rollerrotatably mounted I on aid holder, and a blade carrier pivotally .pivotsoi' the carrier, said carrier being adapted to support a blade with itsedge to be sharpened in position to be engaged by the liattened portionof the roller to be dellected and supported thereby against a sharpeningelement.

6. In a sharpening device, the combination with a handle, a rollerrotatably mounted on said handle, and a blade carrier pivotally mountedon said roller, the axis of the carrier being spaced radially from theaxis of the roller, stops limiting the relative movement of the rollerand carrier, the carrier being adapted to support a blade with its edgeto be sharpened adjacent the roller .and the roller having spaced bladeengaging parts.

In witness whereof I have hereunto set my hand. y
